50 POINTS + BRAINLIEST IF CORRECT. Which of these statements about ocean water is always correct?

a.) Its area is less than the area of freshwater.
b.)Its salinity is less than the salinity of freshwater.
c.) Its density is greater than the density of freshwater.
d.)Its temperature is greater than the temperature of freshwater.

Explanation:

Seawater is denser than both fresh water and pure water because the dissolved salts increase the mass by a larger proportion than the volume.

The freezing point of seawater decreases as salt concentration increases.

C.) Its density is greater than the density of freshwater.

Explanation:

Average density at the surface is 1.025 kg/l. Seawater is denser than both fresh water and pure water (density 1.0 kg/l at 4 °C (39 °F)) because the dissolved salts increase the mass by a larger proportion than the volume. The freezing point of seawater decreases as salt concentration increases.

I'm not sure it could also be D

a. as the temperature increases, the kinetic energy of the gas molecules increases & the molecules move faster & further away from each other.

b. if you decrease the temperature of a fixed amount of gas at constant pressure, the combined gas law reduces to charles's law. in this case, volume will also decrease.

a time line cause it goes from 685 to 978
